Description

Technical Field

[0001] The utility model relates to the technical field of garbage leachate treatment, in particular to a garbage leachate solid-liquid separation device. Background Art

[0002] Landfill leachate refers to a highly concentrated organic wastewater formed by the water content of the landfill's own garbage, rainwater, snow, and other water entering the landfill, minus the saturated water holding capacity of the garbage and overburden, and then passing through the garbage and overburden layers. During leachate treatment, the leachate and garbage must be separated. A search revealed a utility model patent with publication number CN217616758U, which discloses a solid-liquid separation device for garbage, comprising a machine, a crusher, a first press, a second press, a liquid waste collection tank, and a solid waste collection tank. When solid-liquid separation is required, garbage is poured into a feed pipe, a motor drives a shaft, and blades pulverize the garbage. The pulverized garbage falls into an inner cavity due to gravity, while the liquid waste flows out through the seepage holes. Simultaneously, the first and second presses compress the garbage, separating as much liquid waste as possible. Finally, the remaining solid waste is discharged through a discharge port, completing the solid-liquid separation.

[0003] The aforementioned patent also has the following shortcomings: when using the first and second pressing machines to compress garbage, it is necessary to prevent garbage from continuing to fall into the inner cavity of the crusher. Otherwise, the subsequent falling garbage waste liquid will affect the solid-liquid separation effect of the compressed garbage, thereby affecting the efficiency of solid-liquid separation. In addition, some of the crushed garbage will still stick together, making it difficult to ensure that the leaked liquid will completely overflow during squeezing. To this end, we have proposed a solid-liquid separation device for garbage leachate. Utility Model Content
